brown; pith white, tinged with green. Fibrovascular bundle forms a 
semi-circular marking on the leaf scar (figs. 3, a, 4). The scaly bud 
and the opposite leaves also serve to distinguish this shrub. It forms 
a terminal bud. 
5. Magnolia Umbrella.—The budsare covered with close villous hairs, 
and short hairs are also found at the tips of the branches. In the leaf 
scars the fibrovascular bundles appear as dots, arranged in two series, 
often confused and not readily distinguished in case the leaf scar is 
narrow (figs. 4, a, 5). The exterior set of dots is the larger. In the 
scaly winter buds, the flowers in October show petals 7™ long; the 
sepals are very distinct; the stamens are 2.5™" long; the styles are 
very distinctly visible. The fruiting pedicel includes a node bearing 
occasionally a leaf (fig. 4c), but usually only a sheathing scale, mor- 
phologically the sheathing petiole (fig. 4 @). The bark is greenish; 
tinged with brown. The characteristic sympodial growth of a large 
part of the branch is due to the abundant flowering tips, which later 
fall off. Sometimes two seeds occur in the cell (fig. 4 ¢). 
6. Liriodendron Tulipifera.—in the leaf scar the outer series of fibro- 
vascular bundles appears as five dots of larger size, arranged at ap- 
proximately equal distances apart (figs. 5 a, 4,c). The inner set of 
fibrovascular bundles varies in number and size. The pith is solid, 
and is composed of portions with large cells, separated by cross-por- 
tions composed of finer cells.—Aucust F. ForerstTe, Dayton, 
Tillea simplex.—The re-discovery of Dr. Gray’s shortia and of Au- 
dubon’s Florida lily are familiar stories to botanists; other plants too, 
belong in the list, though not lost for so long; Potamogeton Niaga- 
rensis, for instance, detected by no one after its discovery by Profes- 
sor Tuckerman, till the late Dr. Morong found it again in the same 
waters. 
I write to put on record that after a lapse of sixty-five years 7 s//@a 
simplex Nutt. has come to light once more in Nantucket, Mass., where 
Oakes found it in 1829. It has been remembered and sought for in 
the course of these years, by diligent and ambitious collectors, natives 
of the island and visitors, as they had opportunity, and Mrs. Mabel F. 
Robinson of Elizabeth, N. J., is at last the fortunate discoverer. WE 
shall never know where Oakes collected his plants as he said nothing 
more than “on the dried borders of small ponds,” but as that most 
accurate botanist used “pond” in the plural number, we hope that 
new localities may yet be found for this rare little thing, of which only 
the gigantic specimens reach two inches in height. 
rs. Robinson spends her summers in Nantucket with her family, 
and her interest in the island flora has led to this fine discovery.
